Bought this because I felt guilty leaving my 50lb australian shepherd at home when I went out motorcycle riding, which is almost every day in the summer. Wasn't sure if it was gonna work or not but it turns out to be a great pack!
Could use some improvements on the buckles and strap hardware (metal instead of plastic) but I'm also using it pretty strenuously. Have nearly 1000 miles of riding with my dog Beau in this, very satisfied. Would strongly recommend!
We were heading to Acadia National Park and wanted to see as much as we could but with Riley being 15 years old and having a leg injury we figured we needed to come up with something to carry her when she needed a break from walking. Saw the Kolossus and immediately ordered it. I added the water repelling treatment and the name tag and the order was complete. Then our departure date was moved up and we needed the pack sooner. I called up customer service, they fast tracked the order and we got the pack before we left and we did some extra sight seeing with Riley because we had the pack. She is still getting use to it as she has always been a high energy Wheaty(think they all are). Need to get her higher up in the pack and we will continue to practice with her in it.
Customer service really stepped up to get us the pack so big shout out to them! Highly recommend these products.
I was a little skeptical about purchasing this sport sack, however I’m so glad I did! It is everything I expected and I’m so excited that I can now bring my pup along for any adventure!
I was a little worried this bag wouldn't fit because my dog is so large. But it fits perfectly. Supports her well and it wasn't hard to get her inside the bag thanks to the K9 sportsack tutorial. She wasn't nervous getting inside the bag and she was a champ while being carried. Highly recommend for large dogs such as German Shepherds.
My pup weighs about 53 pounds and is just getting a little older to handle the mileage, but still wants to be included! The extra support in this pack definitely made the carry easier and more comfortable and the vents helped her out as it's been roasty around here lately. Both dog and dog-mom approved!
